Robocalls

Hacked social accounts can be used for mass advertising (spam) and as an avenue to lure people to sites that install malware on additional computers. It's surprisingly lucrative.

I have also noticed that there's been an increase in spammer accounts signing up here (but it looks like you guys keep taking them down, too! ). Wonder if that's related to the increase in spam phone calls, like maybe more companies are doing them as some kind of shady business. "We'll robocall people to sell your scam and also flood Internet forums with links to your sites"

Automated spammers are as numerous as the computer hardware running them allows.

It's actually surprising that spammer activity hasn't brought the Internet down yet. Enough measures have been put in place to at least slow them down a little.

Getting back to the robocalls for a moment, I have noticed fewer of those kinds of calls on my phone here lately (last couple of months). Maybe there's something automatically catching them in the phone system now.
